Apple Releases Safari Technology Preview 148 With Bug Fixes and Performance Improvements

Apple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced in March 2016. Apple designed the ‌Safari Technology Preview‌ to test features that may be introduced into future release versions of Safari.

Safari Technology Preview Feature
‌Safari Technology Preview‌ release 148 includes bug fixes and performance improvements for Web Inspector, CSS Container Queries, CSS, Forms, Animations, JavaScript, Rendering, Media, Web API, Security, Loading, WebDriver, and more.

The current ‌Safari Technology Preview‌ release is built on the Safari 16 update and it includes support for feature coming in macOS Ventura such as Live Text, Passkeys, Web Extension improvements, and more.

The new build of ‌Safari Technology Preview‌ is compatible with machines running macOS 13 Ventura, unlike prior versions of ‌Safari Technology Preview‌, but it no longer works with macOS Big Sur.

The ‌Safari Technology Preview‌ update is available through the Software Update mechanism in System Preferences to anyone who has downloaded the browser. Full release notes for the update are available on the Safari Technology Preview website.

Apple's aim with ‌Safari Technology Preview‌ is to gather feedback from developers and users on its browser development process. ‌Safari Technology Preview‌ can run side-by-side with the existing Safari browser and while designed for developers, it does not require a developer account to download.

The big improvement for me that I noticed in the update notes is being able to edit suggested passwords. There’s always that one website that thinks hyphens or non-alphanumeric characters aren’t acceptable, so being able to alter the suggested password is very useful.

Apple lets Safari lag far, far behind other browsers. EU & Feds start asking questions, and Apple lights up the hiring boards looking for browser engineers. Tim is a good ops guy, but cannot see the forest whilst harvesting its most profitable trees. Fingers crossed Apple is forced to allow other browser engines to power browsing on iOS & iPads. It is really hard to argue that Apple's M$FT-like monopoly on the pad/phone browser app is good for us -- but I am sure many here will flame me with reasons why this is so.
I actually like Safari a lot, it's speedy and the integrated passwords with keychain is excellent - including having your passwords in iOS as well.

(I do run Brave as well for Web3 stuff, but I always come back to Safari for main browsing).

I guess, you said it, it must be so. I actually did a browser benchmark test after google (chrome sucks!) bragged about being so fast. Not sure how they doctored their results, but on my m1 MBP, safari and Safari technology preview blew away brave, chrome (didn’t come close to breaking 300 on speedometer as they claimed) and poor Firefox was dismally last. So there is that. Fast, features work. Never confuse personal preference for actually being better or worse, that is not opinion (opinions are based on facts), that is just feelings

Send your 5th birthday wishes to this WebKit bug - it'll be turning 5 years old this July 28th! ??
Bug 174931 ('https://bugs.webkit.org/show_bug.cgi?id=174931') - Implement RegExp lookbehind assertions

Safari is the ONLY major browser that doesn't support this ES2018 feature!? You can look here ('https://kangax.github.io/compat-table/es2016plus/') and it's just this sad little island of red. Why won't they implement this?
